    Abstract: A prosthetic hand with a waterproof cover and/or a filament-based digit securement mechanism. A first annular recess on the digit aligns with a second corresponding annular recess on a chassis to form a groove into which the filament is inserted. The prosthetic hand may comprise a waterproof cover that protects the interior components of the prosthetic hand. A thumb cover and a dorsal cover attach to a palm cover. A thumb cover interface is adhered via a clamp with an exterior sealing ring. A dorsal cover interface has a sealing ring. The thumb cover may be flexible and have three layers. The dorsal cover may be rigid and have a latch that snaps onto the chassis. The cover may be put onto the palm portion with the thumb and thumb cover, and then the prosthetic digits may be attached to the chassis thereafter.
